Firefox Support Forum

ive built a new pc and have a flashing program popup every 10min. upon assistance from a really good pc guy, we've found its a firefox default browser agent with a long code.

its not listed in my scheduled tasks, eyt runs every 10min. only thing close to firefox would be thrunderbird, but iirc, mozilla and thunderbird are not longer the same company. either way. i need this thing to stop running every 10min.

On my Macbook Air M1, Firefox's UI and default scaling is perfect on my Retina display, but if I move the window to my external Philips 1080P monitor, some - but not all - interface elements are very over-sized, which makes Firefox unuseable on any external monitor I connect. (I have tested this with multiple other monitors)

Whenever I try going on to a multiplayer (e.g. .io) game website it will not let me access its server. The website itself works fine and I can access it but as soon as I press play or anything else it just says 'disconnected' or 'trying to reconnect to server'. please see if you can fix this as I couldn't find anything to resolve this problem do anything.

slow browser takes long time to change screens & i have hi speed inernet & side skrool bar works half the time &stay loged in dont work makes you log in evertime fix website

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

I have scoured the web and read/tried everything. I cannot remove the time and date stamp from my documents. No matter what program/app they are printed from it shows up ruining my printing. I've tried unchecking the header/footer box. There's nothing in my brother printer set up regarding the date/time stamp. It has to be firefox. How do I fix this? I'm not a computer guru so I need details. I'm at my whits end! Thanks!

I've noticed that when logging into various websites, a random email address not known to me appears in autofill among my usual email addresses. This unfamiliar address is under the @shanreto.com domain and shows up across different websites. My Firefox account is synced between my PC and mobile phone. Both devices are password-protected and under my control at all times, and I have only installed uBlock Origin as an extension.

Could there be any explanation other than the possibility of someone accessing one of my devices through malicious software or similar means?
